HENRY H. HULL, OF BERGEN, NEW YORK.

Specicationforming part of Letters Patent No. 119,361, dated September26, 1871.

To all whom it may concern:

Be it known that I, HENRY H. HULL, of Bergen, in the county of Geneseeand State of New York, have invented certain new and useful Improvementsin Clod-Breaking-and-Pulverizing Machines; and I do hereby declare thatthe fol lowing is a full, clear, and exact description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon which form part of this specification.

The nature of my invention consists in the construction and arrangementof a combined elodcrusher, pulverizer, and road-scraper, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure lis a perspective view, and Fig. 2 a side elevation of @mymachine.

A A represent four beams, of suitable dimensions, placed parallel witheach other and connectedtogether by means of three bars, B B, passingthrough said beams. Upon one side, or

rather edge, of each beam is attached a rounded iron bar, C, while from.the other edge project steel plates D. The rounded bars C C are to beused down after plowing to level and pulverize the ground. And theplates D D are used down for pulverizing, leveling, and iilling up thedead furrows, cutting up and destroying all grass and weeds preparatoryto sowing, and for scraping and preparing turnpikes and highways. E Erepresent two guides, placed in triangular pieces of wood a, a, casedwith sheet-iron or other suitable material, so that said guides (orrudders) may be pressed down to guide the machine, or drawn up atpleasure. They are confined by pins b b passing through the casings.Through one of the outside beams A, near one end, are two inclinedmortises, d d, through either one of which the clevis is to be insertedand fastened on the inside of the beam by a pin passing down throughsockets e attached on the inner side of said beam.

Havin g thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The beams A A, constructed with rounded surfaces C C, and provided withthe projecting plates D D, thus forming a reversible scraper andpulverizer, substantially as set forth.

p wIn testimony that I claim the foregoing as my own I affix mysignature in presence of two witnesses.
